Description of Business	Description of Business CommerceHub, Inc. (together with its subsidiaries, "CommerceHub," the "Company," "us," "we" and "our") was founded in 1997 (as Commerce Technologies, Inc., our predecessor entity) and is headquartered in Albany, New York, with additional locations in Seattle, Washington and Hertford, England. We are a leading provider of cloud-based e-commerce fulfillment and marketing solutions that integrate supply, demand and delivery for large retailers and consumer brands, manufacturers and distributors (collectively, "suppliers"). Our end-to-end solutions are provided through the CommerceHub software platform, a hub that streamlines integration and enables more efficient transactions among our retailer and supplier customers and their other trading partners, while also enabling them to access the online marketplaces, search engines, social and product advertising and other digital marketing channels (collectively, "demand channels") where consumers browse and buy. Our solutions also help our customers integrate with the third-party logistics ("3PL") providers, including fulfillment and delivery providers, that take purchased products to the consumer's doorstep. During November 2015, the board of directors of Liberty Interactive Corporation, our former parent company ("Liberty" or "Parent"), authorized a plan to distribute to the holders of Liberty's Series A and Series B Liberty Ventures common stock, shares of CommerceHub (the "Spin-Off"). At the time, CommerceHub was a newly formed Delaware corporation that, pursuant to an internal restructuring, effective July 21, 2016, became the parent of Commerce Technologies, LLC, a Delaware limited liability company that, as a result of the restructuring, is the successor to Commerce Technologies, Inc. ("CTI"), the entity through which CommerceHub transacted prior to the Spin-Off. The Spin-Off was completed on July 22, 2016 and was effected as a pro rata dividend of shares of CommerceHub to the holders of Series A and Series B Liberty Ventures common stock of Liberty. The Internal Revenue Service has completed its review of the Spin-Off and has notified Liberty that it agreed with the nontaxable characterization of the Spin-Off. Following the Spin-Off, CommerceHub now operates as a stand-alone publicly traded company, and neither Liberty nor CommerceHub has any stock ownership, beneficial or otherwise, in the other.
